I'm building a new motor for my truck and I probably will build the 351w up but I wanted to hear your opinions on both of them since one being a small block and the other a big block.. is a 360 or 390 gonna kill me for gas mileage? How much more than the 351? Power differences? Which one do you thunk is better? Also the year of the 351 is an 83 and the 360/390 I have a 360 that is a 1969 out of an f350 and the other motor as it is not mine just yet is an early to mid 70s motor I believe.. it's out of an f250

 

This should help.

For what it's worth, I'm pretty sure you could make close to the same horsepower out of either engine, but the Windsor would be much cheaper.

A friend built a 390 for his 69 Mustang several years ago and he had a heck of a time finding a good block. Cylinder wall cracking seemed to be the problem.

I don't recall anybody saying anything kind about fuel mileage with the 360 in early pickups.

 

Not to mention those 360/390 engines will not bolt to your existing transmission. The you have to figure out the belt drive system to run the power steering, alternator, A/C if you have it. Way more trouble than it's worth. I am a fan of the Ford 390 FE engine. I would not take a 360 even if someone gave it to me.

 

The FE is a hard fit into the 80-96 era trucks, so expect a lot of work to shoehorn one in.

Stroke the 351w and leave the FE stuff to the older trucks.

 

How come u wouldn't take a 360? I got one in the farm truck and I think it's real good not including gas mileage

 

How much would stroking the 351w cost?

 

I just never liked that bore/stroke combination in a few different trucks I have driven over the years. The 360 I had in my old 1976 F350 dump truck was gutless for the gas mileage I got out of. Yes I know...it was a dump truck.

A good friend used to have a 1976 F150 with a 360 that was a dog so we dropped in a 390. It completely changed that truck's character.

Hmmm... that's interesting cause the 360 I have is in a 69 f35p dump truck and it spins the dual tires so it definitely don't feel gutless to me haha

 

Good god that's expensive... and I only looked at the 357 so far... I'll either be saving money for a long while or just not stroking it

 

For me the only difference was the price of the crank, which at the time was a little over $250. Now I think they're a little over $300 for an Eagle crank. Pistons are 302 pistons vs 351w. They're just KB hyper eutectic pistons, nothing fancy. I think my whole shortblock was around $2,200 with balancing, assembled. A plane Jane factory rebuild was like $1,600 but had cast pistons and no balance. What you're looking at is complete rotating assemblies with rods, pistons and rings and bearings. Forged pistons will be more and the 408, etc, kits will be more. The 357 and 393 kits use more common pistons, the 393 kit using the 302 pistons. Stroke is 3.850.

I don't have mine in the truck yet. I didn't have anywhere to work on the truck till now, but I'm still not fully moved in. I'm hoping to get it going this spring/summer. I can say the machine shop said it balanced up real nice.

 

1968/76 F100/350 360/390: The block and heads are the same as is the bore (4.05"), the stroke is different. 360: 3.50" - 390: 3.78."

So, all one needs to do to convert a 360 to a 390, is by installing the 390's crank, rods and pistons.

 

That's good. So the 393 is probably the best way to go if I stroke it?

 

For me it seemed like the better way to go. I only needed a cast crank and hyper eutectic pistons so the prices were much better than the 408 kits. Now when you add forged pistons the prices get closer and if you add a forged crank it's really not that different, but for an inexpensive stroker the 393 seems like the hot ticket. Just watch your compression ratio. Summit Racing has a calculator. I went with around 9.5:1, but I'm trying to build kind of a hot motor. For more of a street motor you might want to go around 9:1 - 9.25:1

 

A 460 is a bigger engine and came stock in 80-96/7 trucks. It fits with room to spare, so I'd wager a 390 would fit no problem.
I'd go with a 460, though. A BB in a truck =
